Abstract
Sm3+-doped alkali-barium-bismuth-tellurite (LKBBT) glass with high refractive index has been fabricated and characterized optically. The refractive index, density, optical absorption, IR transmittance, Judd-Ofelt parameters and spontaneous transition probabilities have been measured, calculated and analyzed. In the LKBBT glass, Sm3+ ions emit intense reddish-orange lights under the excitation of long-wave UV and blue lights. Absorption and excitation spectra indicate that commercial UV and blue laser diodes, blue and bluish-green LEDs and Ar+ optical laser are powerful excitation sources for Sm3+ visible fluorescence in the glass with high optical refractive index.
